Abstract

The content of this article is the proposal of process of the safety analysis for complex dynamic systems. The safety analysis is carried out in process of the proposal of control system for safety-critical processes. In preliminary hazard analysis is done the identifying all possible risks by PHI method. The PHA method is used to analyze these risks. The method of safety analysis depends on various safety-critical states of system which are system are controlled by models. We propose to use the method SQMD for modeling these states. This method combines qualitative and quantitative methods of modeling states and takes advantage of both methods. The model of the proposal is shown in the diagram. The article includes detailed description of the tasks for each step of analysis.
